Photocatalytic air purifier

Abstract

The invention belongs to the field of purifier, and more specifically relates to a photocatalytic air purifier. The photocatalytic air purifier comprises an ultraviolet lamp, a catalyst storage box, apurifying structure, an air suction structure, a filtering structure, and a dedusting structure; the purifying structure used for purifying the air is connected with the catalyst storage box which isused for storing a catalyst; an air suction fan main body is turned on for suction of air into an air purifier main body, and driving of a fixing rod to rotate at the same time, a limit block is pushed, so that sliding of a first filter screen in a chute is realized, and dust falls onto a dust collecting tank through vibration; a spring is adopted to realize back and forth sliding of the first filter screen, in sliding process, a rubber block is pushed, so that air in the chute is blew onto the first filter screen through a gas outlet pipe, dust on the first filter screen falls onto the dustcollecting tank further, a second filter screen is adopted to prevent suction of dust into the chute, the first filter screen is driven to slide to drive a fixing plate for back and forth sliding, sothat a dust scraping plate is driven to slide back and forth in a protection hood 63 to scrape dust into a dust discharge tank and remove dust through scrapping.

Description

technical field [0001] The invention relates to the field of purifiers, in particular to a photocatalytic air purifier. Background technique [0002] The photocatalytic air purifier is to coat the catalyst on a specific carrier and irradiate the catalyst with an ultraviolet light source of a specific wavelength. Through the action of the fan, the air containing harmful gas passes through the catalyst at a specific speed, and the catalyst on the carrier reacts chemically with the harmful gas under the irradiation of ultraviolet light to achieve the purpose of purification. [0003] When using a photocatalytic air purifier in some rooms under renovation, due to the large amount of dust in the room, the air inlet of the photocatalyst will inhale a large amount of dust. The filter inside the photocatalytic purifier is fixed. As a result, it is difficult to enter the air inlet, which reduces the air evolution effect of the air purifier, and has a certain impact on the life safet...

[0003] When using a photocatalytic air purifier in some rooms under renovation, due to the large amount of dust in the room, the air inlet of the photocatalyst will inhale a large amount of dust. The filter inside the photocatalytic purifier is fixed. It makes it difficult to get air into the air inlet, reduces the air evolution effect of the air purifier, and has a certain impact on the life safety of construction workers
